My invention relates to improvements in transportation means, and morespecifically to chocking means for use on railway cars in connectionwith motor trailer equipment.

The invention is designed with the primary object in view of providingimproved equipment for transporting motor trailers on railway cars,

the improvements being directed particularly toward facilitating loadingof such trailers on railway cars, as well as to securing the trailer onsuch cars against casual displacement either laterally or longitudinallyof the cars, and also against upsetting, all without prohibitivelyincreasing cost of manufacture and maintenance of such equipment.

Other and subordinate objects, also comprehended by my invention,together with the precise nature of my improvements, and the advantagesthereof, -will be readily understood When the succeeding description andclaim are read with reference to the drawings accompanying and formingpart of this specification.

' In said drawings:

Figure l is a view in side elevation of my invention in a preferredembodiment thereof,

Figure 2 is a view in top plan with the trailer removed from the car.

Reference being had to the drawings by numerals, according to myinvention, a railway car I, for carrying a truck trailer 2, is provided,which is of the commonly designated flat-car type and embodies a flatbed 3 carried by side sills 4 supported by wheel trucks 5, the wheels ofwhich run on the usual rails 6. The car I is provided with suitable endcouplers I and air hose couplings 8 also with a brake cylinder 9 foroperating brakes I0, all as conventional. A particular feature of myinvention is that the wheels I I of the trucks 5 are designed to berelatively smaller than the standard railway car wheels and the sills 4set low on the trucks 5, all to the end that the bed 3 is disposed at alower level with respect to the ground than 'the usual flat car, so thatthe trailer 2 may be loaded onto and unloaded from the bed 3 from a lowramp, dock, or the like, not shown.

The trailer 2 is of the closed-body, tractordrawn t pe, with a singlepair of rear wheels I2 and a wheel-equipped, front-supporting jack I3which may be of any conventional form for adjustment into anout-of-the-way position when not in use. The numeral I4 designates theusual hitch for coupling the trailer 2 to a suitable tractor, not shown,for pulling the same over the road.

Pairs of elongated, bevel-sided chock blocks I5 are provided on one endof the bed 3, one pair adjacent each side of said bed, for the wheelsl2, the blocks I5 being spaced apart in each pair 1ongitudinally of saidbed and extending crosswise of the bed when in use. A single chock blockI5 is provided adjacent the opposite end of the bed 3 for the wheel I!of the jack I3 between said end of the bed and said wheel. The pair ofchock blocks I5 are provided with reduced ends l8 pivoted on the bed 3,as at IS. The pivots I9 of the pairs of chock blocks l5 are spaced apartupon opposite sides of the longitudinal center of the bed 3 a distanceless than that obtaining between the wheels I2 so that said blocks maybe swung out of chocking relation into a position between said wheels,for instance, as shown by dotted lines in Figure 2. Pairs of arcuatedetent bars 20 are provided on the bed 3 for the pairs of chock blocksI5 and arranged at the outboard sides of the Wheels I2 to receive, inselective longitudinally spaced apertures 2I therein, detent pins 22inserted through suitable apertured reduced ends 23 provided on the pairof chock blocks I5. The chock block I6 is identical with the chockblocks I5 being pivoted, as at 24, on the bed 3 and provided with adetent pin 25 coacting with a detent bar 26 identical with the detentbars 20.

Chain anchor means is provided in conjunction with the foregoing forpreventing the trailer 2 from upsetting and comprising the following. Aneye bolt 21 is suitably secured in the bed 3, in the approximate centerthereof, with a swivel ring 28 therein to which two pairs of chains 29,30 are suitably secured for extension toward opposite ends of thetrailer 2 in upwardly inclined, divergent relation in each pair tolaterally spaced front and rear pairs of U fasteners BI, 32 provided onthe bottom of the trailer 2. Suitable hooks 33 are provided on thechains 29, 30 for attaching the same to said fasteners 3 I, 32

As will be seen, the chains 3|, 32, in addition to anchoring the traileragainst upsetting, also prevent forward and rearward movement of thetrailer 2 on the bed 3 when the chock blocks I5, I6 are swung intowheel-releasing positions, whereby the trailer 2 cannot rol1 until thehooks 33 are disengaged from the fasteners 3!. Thus. a safety factor isprovided reducing accident hazards, as will be manifest.

In the use of the described invention, in loading the trailer 2 onto thebed 3, the appropriate chock blocks I5 of the pairs are first moved intoeffective position, in a manner which will be clear, and the trailer 2backed onto the bed 3 against said blocks, thus set. The other chockblocks 15 of the pairs are then properly positioned in front of thewheels II. The jack I3 is then lowered, and the chock block l6 movedinto chocking, or blocking, position, in front of the wheel H. Thechains 29, 30 are then attached to the fasteners 3|, 32. A particularadvantage of the detent bars 20 is that the chock blocks IS-may be setinto either angular or straight position to chock wheels of differentdiameters; likewise the chock block is may be set into chocking relationto jack wheels I! of diflerent diameters, all by merely inserting thepins 22, 25, as the case may be, in selected apertures2l or 26.

The foregoing will, it is believed, sufiice to impart a clearunderstanding of my invention without further explanation.

Manifestiy, the invention, as described, is susceptible of modificationwithout departing from the inventive concept, and right is hereinreserved to such modifications as fall within the scope of the appendedclaim.

What I claim is:

Chocking means for a fiat bed railway car com- 5 4 prising elongatedchock blocks, means to mount said blocks in complemental pairs .atopposite sides of said bed to extend crosswise o! the bed in each pairwith the blocks in each pair swingable into different angular positionswith respect to each other to vary the checking relation thereof, andmeans to lock the chock blocks of each pair in diflerent angularpositions comprising arcuate apertured detent bars, and pins carried bysaid blocks for extension through said apertures selectively.
